Scientists studying ancient ocean fossils found that the Arabian Sea was better oxygenated 16 million years ago, even though ...

Earth’s oceans reached their highest heat levels on record in 2025, absorbing vast amounts of excess energy from the atmosphere. This steady buildup has accelerated since the 1990s and is now driving ...

A new study suggests the world's oxygen-depleted seas may have a chance of returning to higher oxygen concentrations in the ...

A global team of scientists reports that Earth’s oceans absorbed more heat in 2025 than in any year since modern observations began. The findings, published today (January 9) in Advances in ...

A new scientific report has shown that global ocean heat content (OHC) increased for the ninth consecutive year in 2025.

Consistently warming oceans have fueled a rash of subtle records, especially on the West Coast. High tides get higher; ...

Every calendar year since 2019, ocean temperatures have reached new record highs. 2025 was no exception, according to a new ...

The ocean stored more heat in 2025 than ever recorded, fueling sea level rise, extreme weather, and growing climate impacts worldwide.

Greenland sits at the center of a striking climate contrast, even as sea levels rise across almost every other part of Earth. As global temperatures climb, glaciers and ice sheets melt faster, and ...

Scientists say the warming of the world’s oceans is accelerating more quickly than previously thought, a finding with dire implications for climate change because almost all of the heat trapped by ...

The rise in Earth's overall temperatures paired with fertilizer runoff is making for ideal growing conditions. Good for ...
